GRIPPING DEVICE IOR DOUBLE-STAVE-VENEER BARREL MACHINES.

SPECIFICATION forming part of Letters Pateht No. 739,363, datedSeptember 22, 903.

Application filed March 11,1903. Serial No. H7376. (No model.)

hereby declare the following to be a full, clear,

and exact description, such as will enable othro ers skilled in the artto whichit appertains to make and use the same.

My invention relates to improvements in machinery for making veneerbarrels from a plurality of veneer pieces; and the especial objects ofthe invention are to provide means for securely bindingthe veneer piecesupon the barrel and for gripping also the inner extremities of thehoops, so that as the drum of the machine revolves the veneer pieceswill be compressed by the hoops, and a complete barrel can thus readilybe formed from various veneer pieces instead of from one large integralpiece of veneer as formerly.

I accomplish my objects by means of the internal springs designed to beprojected at the will of the operator and adapted to extend over andcompressthe inner extremities of the hoops upon the first piece ofveneer introduced into the machine.

My invention further consists in the combination and arrangement of thevarious parts, as hereinafter described, shown in the accompanyingdrawings, and specifically pointed outin the claims. V

In the accompanying drawings, Figure 1 is a perspective View of amachine adapted to accomplish my objects. Fig. 2 is an end view of thedrum. Fig. 3 is a similar viewshowing the compression-roller down and'inthe 40 act of raising the extremities of the springs so that the hoopscan be introduced thereunder.

In the views, 1 is the veneer-coiling drum,

similar to those now in use. 2 is the shaft 5 therefor, and 3 theoperating-gear.

4 is a roller longitudinally mounted on a bearing 5, which reciprocatesvertically in guides 6 and is manipulated by means of the shaft.

'mon support upon the drum-shaft, a handle lever 7 and the weight 8.This roller is of less width than the slot or narrow opening 9, runninglongitudinally of the drum 1.

The springs 10 are curved to conform to the circle of the drum cylind'erand are attached to the bars 11, which are diametrically placed withinthe cylinder and sleeved at 12 over the A bar 13 connects the outerextremities of the diametrical bars, and a handle secured thereto servesto throw the springs within or without the cylinder, asrequired.

In operation a piece ofveneer r being placed within the slot underneaththe. springs, as shown in Fig. 2, the roller is then brought down uponthe springs directly over the opening between the body of the drum andthe edge of the collapsible portion 14 thereof. The depression of thespringsin the opening against the edge of the collapsible portion of thedrum causes the free extremities of the springs to rise, asseen in Fig.3, so that the ends of the hoops II can be inserted underneath them. Thedrum being then rotated, the hoops fed through guides 15 are heldrigidly by the springs, which at once grip the hoops closely as soon asthey are released. Two men usually attend one machine, one in the rearnailing the veneer strips and hoops together as the drum rotates.

By means of this device barrels can be formed of narrow or scrap piecesof veneer, and thus more economically than from single pieces of veneer.

Having described my invention, what I claim as new, and desire to secureby Letters Patent, is- 7 v 1. In combination, a veneer-coiling drumprovided with a collapsible portion separated from one edge of the drumby an open slot, 7 curved springs within the -drum concentric therewith,rotatably supported upon a comupon the support for the springs by meansof which they can be rotated so as to project be yond the edge of thedrum over the open slot and slightly over the edge ofthe'said'collapsible portion, upon which they find a bearing, and meansfor raising the outer extremities of the springs so that thebarrel-hoops can be inserted thereunder, substantially as do scribed.

2. In combination, in a veneer-barrel machine, a veneer-coiling drumprovided With a collapsible portion separated from one edge of the drumby an open slot, means for securing the first of a succession ofveneerpieces to the drum and for simultaneously binding the extremitiesof the hoops thereon, consisting of curved springs Within and concentricwith the drum, a common support for the springs rotatably secured to thedrum-shaft, means for rotating the support to project the extremities ofthe springs beyond the edge of the drum across the open slot and overthe BERT W. TRUSCOTT.
